Like numerals of reference indicate like parts throughout the different views.

Referring to the drawings, l, l are depending bars or members mounted for independent oscillatory movement upon some lixed part of the cultivator or other implement or vehicle, either the frame or tongue, in the present instance being shown as mounted upon the tongue 2. These oscillatory bars may be mounted in a variety of ways, in the present instance being shown as mounted uponthe pivot rod 3 held in a casting or the like i fixedly secured to the tongue. Any other convenient form of mounting, however, may be employed. The lower ends of these oscillating bars are provided with openings or the like 5 for the attachment of chains or other ligaments G, the other ends of the which are connected with the gang frame T. The form of ligament and the manner of connection is immaterial. The ligaments are, in practice, such as to permit of adjustment thereof so as to vary the distance between the lower ends of the oscillating bars and their point Vof connection with the gang frame. This may be readily done by changing the links of a chain or the adjustment of a strap or bar in any well known way.

The gang frame and other portions of the cultivator may be of any of the well known or approved forms of construction, that herein shown being merely for the purpose of illustration to show the application of my present improvements. A detailed description, therefore, of these parts is not deemed necessary further than to state that 8, 8 are side bars of the frame, 9 the mast, l0 the pendulum bar, 11 the lifting bar and l2 the lever employed for raising and lowering the gangs. In Fig. l the full lines represent the position of the parts when the gangs are down in operative position. The dotted lines indicate the position of the parts when the gang frame is raised and the earth-engaging implements out of operative position.

My present improvement is capable of embodiment in a variety of forms, some only of which are heroin illustrated, and upon reference first to Figs. 2, 3 and it there will be seen a yoke, the side bars 13 of `which To all 'ze/mnt 'it may concer/t Be it known that I, HENRY PieTnnsEN, a citizen of the United States of America, and resident of Mount Auburn, in the county of Benton and State of Iowa, have invented certain new and useful Improvements in Draft-Equalizers, of which the following is a specification.

This invention relates to certain new and useful improvements in draft equalizers and it has for its objects among others to provide a construction whereby I can obtain the maximum amount of movement of the doubletree or evener bar for the hitch of the draft animal, and to apply all of the draft strain to the depending oscillating bars and then divide such strain between the main frame and the gang frame. I connect the doubletree or evener bar with the oscillating bars independently of each other for independent movement of the gangs, and in some instances provide a carrier and ,guide support for the doubletree or evener bar, and mount the same so as to minimize `the fricton. I provide for the lateral adjustment of the oscillating bars to control the crowdine .in or out of the gangs. i By applying the draft strain partly on the main frameand partly on Vthe gang frame, I am enabled to hold the earth-engaging members down steady against their work. The depending bars are mounted to oscillate independently of each other in the direction of the draft strain to the extent of the movement of the gang frame in the line of draft.

Other objects and advantages of the invcntion will hereinafter appear and the novel features thereof will be particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the numerals of reference marked thereon, form a part of this specification, and in which Figure 1 is an elevation showing the application of my present invention to one form of cultivator. Fig. 2 is a perspective view of the parts embodying my present invention. Fig. 3 is a fragmentary view with portions broken away and parts in section through the pivot of the doubletree orl evener bar. Fig. 4 is a perspective detail of a portion of one form of yoke. F ig. 5isa perspective view showing a slightly modified form. Fig. 6 is a perspective detail showing a modiiied form of yoke with oscillating at 14, with the and also independent of the equalizing bar depending oscillatory bars 1 at a Ypoint at ldand the doubletree or evener bar 18, the or above the center of said depending bars, strain from the doubletree 18 is equally sussuitable means, such as the plurality of tained by the oscillating bars 1, 1.

While in the present instance I have shown my improvements with the parts so disposed that the doubletree or evener bar 18 is to the rear of the depending' oscillating bars i, it is evident that the position of the parts may be reversed, that is, turned end for end so that the doubletree or evener bar 18 will be in front and the depending bars 1 to the rear. In this reversed position the operation is practically the same and a like result attained.

h/[odifications in detail, proportion of parts etc. may be resorted to Without departing from the spirit of the invention or sacrificing' any of its advantages.
